GPS data from XMP to Exif

[Archive]

Hi,

I have XMP file, containing:

Code:

...
 <exif:GPSLatitude>43,41.73866N</exif:GPSLatitude>
 <exif:GPSLongitude>7,16.53864E</exif:GPSLongitude>
...

I can copy GPSLatitude from Src.XMP to Dst.JPG, for example:

Code:

exiftool -tagsfromfile Src.XMP "-exif:GPSLatitude<xmp-exif:GPSLatitude" Dst.JPG

-but when doing this, only Exif:GPSLatitude is copied from XMP. How do I copy "N" (in this case) into Exif:GPSLatitudeRef tag?

Just a though in this regard: if at all, then usually all GPS tags are needed to be copied. In such case, it would be great having something similar to "AllDates"... something like:

Code:

exiftool -tagsfromfile SrcFile "-Exif:AllGPS<xmp-exif:AllGPS" DstFile

Thanks for answering.

Hi Bogdan,

You need to also copy the GPSLatitudeRef, ie)

Code:

exiftool -tagsfromfile Src.XMP "-exif:GPSLatitude<xmp-exif:GPSLatitude" -gpslatituderef Dst.JPG

Doing this will copy the Composite:GPSLatitudeRef to EXIF:GPSLatitudeRef, which
is what you want.

The tag shortcuts wouldn't work for this purpose unfortunately.  In this
case, a .args file and the -@ option is the way to go, as is
done when translating IPTC to XMP.

Thank you very much -exactly what I needed :-)

I just realized that you can do what you
want with just one argument:
"-all>gps:all".  I think this should copy
all xmp gps to the exif gps.  - Phil

I had forgotten many of the details of these conversions since
I looked into them years ago.  (Perhaps I should document some
of this.)  But I forgot about the XMP:GPSDateTime difference,
so the Date/Time stamps must be handled specially.

# translate from XMP to EXIF GPS

exiftool "-gps:all<all" "-gpsdatestamp<gpsdatetime" "-gpstimestamp<gpsdatetime" ...

Note that exiftool will be smart and copy the date part of GPSDateTime
to GPSDateStamp, and the time part to GPSTimeStamp (a bit of magic here).

# or you could specify the "all" tags more explicitly to reduce the
work that exiftool must to to check all tag names:

exiftool "-gps:all<xmp-exif:all" "-gps:all<composite:all"
"-gpsdatestamp<gpsdatetime" "-gpstimestamp<gpsdatetime" ...

# or to copy from EXIF GPS to XMP:

exiftool "-xmp:all<gps:all" "-xmp:gpslatitude<gpslatitude"
"-xmp:gpslongitude<gpslongitude" "-gpsdatetime" ...

Here, the GPSLatitude, GPSLongitude and GPSDateTime must
be copied separately since these tags are different format in the XMP
but are provided as Composite tags for this specific purpose.

Thank you. This very usefull to know when dealing with GPS data -and my "examples" file is growing and growing :-)

Greetings,

Bogdan
